To all whom it may concern.

Be it known that I, VICTOR ALEXANDER Rm'r on, a subject of GrcdtBritain, end' be rendered incandescent when the lamp is in use, anditconsists 1n the novel features,

structure and combinations of parts hereinafter described, end moreparticularly pointed out in the claims.

The objectof my invention is to provide an improved lamp having ageneral appearance npproximatlng that of an electric arc lamp androvided with inverted burners and suspen ed mantles.

Referringto the accompanying drawings: Figure 1 is a side sectional Viewof the lamp; Fig. 2- is a modification of the same lamp; Fig. 3 is aview partly in section, of the multiple burner; l ig. 4 is a top plan ofthe burner; Fig. 5 is a bottom plan of the burner; Fig. (5 is anenlarged view 'of the gas-and air mixer, showing part of the antishockdevice; Fig. 7 is a top plan'of the mantle plate showingthe guides 15;Fig. 8 is n bottom plan ofthe mantle plate, art of it being removedfor-convenience -o .dravw ing; Fig. 9 is stop section on the'line AA ofFig. 1; Fig. 10 is an enlarged sectional view of *t-he. supporting rodFig. '11 an alternative to Fig. 6; Fig. 12 shows art of u mantle platewith the mantle ho der in position.

In the drawings 9 designates the exterior shell df the lamp 25 a,chimney therein, 10 the burner, 13 t .ma'ntle supportin plate, 100 aglass lob'e rotecting the mantles and suspended rom t e'lower edge ofsaid exterior 'shell,'1 the gas-supplyi e from which the lamp issuspended, 2 8'50 low ball coupling screwed onto the lower end of saidits vertical branch "with a-menually ope'rplate,

a'tive'valve fitting 5 for opening and closing the gas passage throughthe some and havingflat its lower end a. controlling nozzle (5 equippedwith a regulating needle 8 and projected Within the outer and la end ofthe said tube 7, which is rigid with the burner.

.The exterior shell 9 will of ornamental. configuration, by preference,and it secured by a screw 101 to a collar 102 on the pipe 1 andby ascrew 103 to the coupling 2, said screws extending horizontallythrougzi'i holes in said shell and the chimney 25 and. serving to did in'suspendin' the cllimncy and securing it in position. lilsuully I shallemploy only the screw 1.03, which is sulficient under all ordinaryconditirms. The horizontal portion of the pipe extends through holes inthe shell 9 and chimney 25 and by entering the coupling 2 aids insuspending t-he lamp and maintaining the proper relation of said shelland chimney to eo-l'zh other. The screw 103. coupling and horizontalbranch of the pipe 5 are amply sullicient for suspending the lamp andpassed directly thrmlgrh the shell and chimney and screwed into theciuipling Q.

The chimney 25 is preferably listed at he lower end, and within theenlarged ion-c:- end of the chimneyds loculed tlu: burner il which Willpreferably be of cast metal and suspended from the coupling 2 by meansoi a ro'd lG,which may, if desired. have inn-rposed between its upperand lmwr parts or sections a cu'shioningspring 1T intended to absorbshocks or-ja'irs. i

The burner lO'is hollow and it has projecting. downwardly from it atecyuiwlisltnut points n series of heads ll which enter and discharge themixed and nir into ihc mantles lil. The burner 10 is provided an oneside with the inlet lube or pipe T, whi h extends horizontally throughthe chinnn-y 25 and'shell 9 and is of bell-shape at its outer end. asshown. The nozzle 6. for {gas projects into the open mouth of-the tube 7and capable of-ready manufacture.

extending a pipe 4 mixture filling the chamber ithin the burner anddischarging through the heads 11.. l preferably provide within theburner 10 a sheet of gauze '22 to aid in compelling av thoroughadmixture of the gas and air. ithin the outer end of the tube 7 andsurrounding the inwardly projecting end of the nozzle. 6, may heprovided a helical spring 18 to serve as a cushioning or shock-absorbingmedium. The burner 10 is provided with a collar 104 and screw 105 forconvenience in connecting it with the rod by' I which it IS suspended.

The mantle support ing plate 13 is in the form of a horizontal diskhaving a central opening or sleeve 27 to he slipped upwardly .upontherod 16,

which in addition to its other duties, serves to properly center saidplate with relation to the burner 10.. lhe plate 10 contains openings-14through which the'mant-les 12- m ay be inserted, the. shoulder aroundthe open upper end of the mantles serving to prevent the mantles. fromescaping downwardly from the plate 13. The plate 13 is formed around theopenings 145 with upwardly extending; flanges 15' to house the upperedges of the mantles. The. plate 13 is adjustably secured in position bya setscrew and hence may be raised and lowered at will. Vithinthe'chimney 25 I preferably provide a protecting wall 2% for shieldingfrom the heatthe coupling 2 and so much of the pipe 3 as may bewithinthe chimney.'

in Figs. 2

and 10 1 show a modification of a portion of my lamp residing mainly incoupling'Q to provide pilot burner-tips 19 for lighting the lamp whenthe gas is turned on by the opening of the valve 5. The flow of gas tothe tips 5 and its flow to the burner regulated by the needle 9. Themixture of gas and air passes through the. tube 7 to the burner 10 andthence through- 12, which. on the liuhtingttof the gas at the heads 11,become incandescent.

My invention provides a la-mp of great effi iency and one of verydurable chara titfir e arran cement of the pipe 3 is a very desirablefeature. since said pipe comprises simply two right-angular branches,with the vertical b anch fully exposed and having the valve 5: andnozzle. 6, while-the horizontal branch may be passed directly throughthe gas, the

downwardly from the.
